SPECIFICATION forming part of Letters Patent No. 531,081, dated December 18, 1 894.

Application filed March 7,189i4- Serial No. 502.775. (No model.)

To all whom it may concern: ward a rod 48, and the ,lower end of a lever Be it known that I, SIMON W. WARDWELL, 49, pivoted at 00 and carrying a lug 52, which J r., a citizen of the United States, residing at enters a slot in the carriage C and thereby Boston, in the county of Suffolk and Stateof carries thelatter toward the pivot of the tongs.

which moves back and forth upon the rods 17, which have a lateral motion upon the ods 20, may be provided with a pawl L, the end of which will engage a rachet uponone of the rods 17. The engaging end of the pawl may be lifted by pressing upon the outer end when the weight W, acting through the parts 0, 49, 48, 45 and. 50, will force the guide 0, against the cop tube. After removing the finger from the pawl it will drop and engage the ratchet, and as-the guide moves along the cop tube any projection upon the latter will force the guide back, and the pawl willp're vent it from moving forward. The cord will. thus be laidjupon the irregular cop tubeand while the first. two layers will be somewhat irregular the cop will soon assume a perfectly cylindrical exterior shape and will be wound throughout the greatest portion of its mass with absolute uniformity.

The devices for limiting the inward movement of the guide may be differently arranged to control any of'the parts connected with the guide. Thus, the pawl'L" may be carried at the end of the lever 49 and engage a curved rack upon an arm 9' extending from the frame of the machine.

While I have shown my invention in connection with parts of a winding machine substantially that of the character illustrated in my aforesaid pateut,I do not limit myself to the particular construction of winding device shown,nor to any special form of engagp iug devices for preventing the inward movement of the guide.

I claim as my inventionv i 1. The combination ina winding machine of a cop holder, a guide movable to and from the axis of said holder, means to re 'procate the guide longitudinally of the axis, and means for preventing the inward movement of the guide after it is moved outward by, and during the formation of, the cop, substantially as set forth.

2. The combination in a cop winding machine, of a cop tube holder, a thread guide and means for reciprocating it opposite to said holder, and devices for carrying the guide against the holder, means for preventing the inward movement of the guide after it is forced outward by and during the building up of the cop, substantially as set forth.

The combination of a cop tube holder, a

reciprocating guide, and means for carrying I it toward the cop, a'snpport for said guide permitting it to move outward solely under the pressure of the increasing size of the cop,

and engaging devices for preventin the inward movement of the guide after ithas been forced outward, substantially asset forth.

4. The combination of the reciprocating I guide, means for carrying it inward and a support permitting the outward movement of the guide, of apawl and rack arranged to permit the outward movement, under the increas: ing size of the cop and to restrain the inward movement of the guide, substantially as set.

forth.

In testimony whereof I, have sign d my name to this specification in the presence of two subscribing witnesses.
